CREAM MINNESOTA, A FIRM COOLER Application filed April 9, 1928. Serial No. 268,497.

My invention relates to a cream cooler having a nature to cool the cream as it runs from the separator. In handling cream it is very desirable to cool the same down to a low temperature just as soon after it has been received from the milking as possible, and by my cooler the cream can be reduced to a very low and practical temperature directly as it runs from the separator, providing a very desirable means for handling cream and preserving the sweetness thereof.

My invention includes a cooler of a simple nature adapted to hold the cooling can within a cooler pail wherein cold water may be introduced and caused to flow through the same if desired, so as to keep the cooling can immersed within the cooling casingand thereby provide a cooler of a very eificient nature.

It is also an object of my invention to provide a spreader for the top of the cooler which functions to spread the cream out and cause it to run down the sides of the cooling can container, which being immersed in the cooling casing, so that cold water or other cold liquid or means entirely surrounds the cream cooling container, thereby directing the cream in thin spread-out streams over 1 the surface of the cream container and rapidly cooling the same by directing-the warm cream closely to the cooling medium surrounding the cream container. A The spreader means includes a cup member from which a series of passageways spread the cream over a frustro-conical cover member which is formed with a series of radiating channels having bifurcated lower ends which discharge the cream in thin streams off of the periphery of the cover or spreader over the wall of the cream can directly adjacent the surrounding. cooling medium.

Another object of my inventionis to provide a means of holding the cream can within the cooling receptacle which forms the outer casing of my cooler..

These features, together with other objectsand details of my cream cooler will be more fully hereinafter described. I

In the drawings forming part of my specification:

Figure 6 illustrates an enlarged detail of the clamping ring.

My cooler A is provided with an outer receptacle and casing lOwhich is-adapted to receive water through the inlet pipe 11 and permit the discharge 0t the water out through the outlet pipe 12. This provides a receptacle 10 for introducing ice cold water into the chamber 13 of my cooler A.

The casing A is formed with spacer members 14 and 15 which are secured in the bot tom of the, casing 10 and are spaced from thebottom 16 of the same in a mannerto support the bottom 17 of the cream can 18 away from the bottom 16 of the casing 10. The cream can 18 is adapted to receive the cream from the separator andis held within the casing 10 by the clamping ring 19.

The clamping ring 19 is of a particular formation having the ends 20 and 21 connected together by the bolt 22. A coil spring 23 presses against the hook end 24 and causes it to bear against the offset portion 25 of the end 20. The end20 is connected to the casing 10 by the bolts 26 which pass through the end 27 of the same to connect the clamping and 21 to the casing 23 operates it causes the sides of the ring 19 a to expand. Virtually diametrically opposite to the ends 20 and 21 ofthe ring 19 I provide aclampingcam 30 which bears against the ofiset portion 31 of one side of the ring 19 tends through'the slot 33 formed in the cam member 30. [The bolt 32 engages the offset portion 3 1 of the other side of the mug 19 sothatwhen the 'cam 30 is engaged byuts handle portion 35 and pulled upwar against and which is held by the bolt 32 which eX the offset portion31, the portions 31 and '34 will be drawn toward each other as illustrated in Figure 3, clamping the sides of the ring 19 against the action of the spring 23 about the upper end of the cream can 18 to hold the cream can with its bottom portion in the cradle formed by the crossmembers 14 and 15. This holds the cream can clamped firmly in the casin 10 and in the cooling chamber 13 so that when cooling liquid is introduced into the same-,thecan will .notfioat even if it is empty. :Oneofthe portionsojf the ring 19 at the operating cam 30 is c011- nected by the bolts 38 to the side of thecasing l0 and thereby holds the side of theclamping ring 19 at the operating cam 30 rigidly to the casing in the samemanneras the bolts 26 hold the other side of the clamping ring ,19. My cooler Aiis provided with a spreader B which is formed with a cupAOpfrom whichdepends a ing portion 41. The cup 40 is formed with a series of outlet openings {12 which direct the cream from the cup lOoutto ,thea'adially extending channels 43 which are formedin the surface of the .frustro-conical portion 41, and these channels 43 are bifurcated into smaller end channels 44: which cause the cream to run off atthe periphery of the, cover and spreader B. The cover 15 iscformedwith a seriesof air openings which may beofany .size;or number such asgt5 so as topermit the .air from the: cream can 18 ,to passcut ofthe same as thecreamruns intothe can from-the cup 40.

Thus .in ;operation of my cream. cooler the cream runs from the dischargepipe of a separator directly :into .the receiving cup 40,, and then the cream is spread .outthrough ,the penings lQ-into the radial. channels .43 .which bifurcate out intotheportions i l andthereby direct :the flow of the warm cream againstthe cold sidewall of the CIIBfilIlgCElIll81WhlQhrlS surrounded by cold water or other ccoling liquid, and Ithereby. coolthe. cream sorapid- ,ly. as it .leavesithe-eream separator as ,toprovide, a very efficient cooling means which operates automatically without extra attention .andpermits, the coolingof the cream inan, eflicientmanner, SOgtllflt, the cream is reduced to the ,propertemperature .to assist keeping it sweet and. desirable, to bestoredawayfuntil it is taken to the market. 7

,My cooleinis ofa simple,natnre andjhere- 'fore; may. be sold ,at a, reasonable price to the .farmer, assisting him i in cooling his cream andiir such a simple eflicient -manper as to make :111 V cooler virtually indispensable to the. farmer for the reason that he can market his cream sweet rathergtlian having it sour,

and. the. fact that sweet cream is much to, be

, preferred, readilyisets, forththe primary. im portance of; lny'fireimlcooler and thevalue of thesame to the fanmeran to the creameries. All of, the parts, of-Jny cooler are readily A separable so that they can be. sterilized, par- .frusto-conicahcover spreadticularly those parts which the cream comes in contact with, and therefore the efficiency and practicability of my cooler is more clearly set forth.

In accordance with the patent statutes I have described the principlesof operation of ,my coolerand while I have illustrated a particular formation and arrangement of the parts, I desire to have it understood that the same areonly suggestive of a means of carryingputirry invention and that changes and variations may be made within the scope of the following claims without departing from the spirit of my invention.
